Ran across this physics article this morning and thought I would pass it on here. Saving historical documents is a big deal and a lot of research continues to find new ways to unearth the treasures and cultures of the past through this medium. In this case it's about daguerreotypes (the earliest form of commercial photography ~1830 and quite deadly chemically).
I rabbit hole'd early photography history about 10 years ago and this is a pretty (although quite expensive) big breakthrough. And I thought working at the pixel level was snow blinding but 10 microns requires more than trifocals.
On a side note, historically speaking, the Synchrotron is a derivative of the cyclotron and was graced in the late 60's to get a tour of the Bevetron (billion electron volts) and control room up on the hill at Berkeley, which is a specific type (derivative) of a Synchrotron for proton acceleration in particle physics research. Just one of the electromagnets which I (6'6") could stand up inside was strong enough to kill you when energized. It also had it's own substation to run it so as not to dim the streetlights in Berkeley.
All this just gives some perspective of how far we've come in our workplaces (capturing a moment in time) and technologies (digital photography) and brings full circle, 50 years for me and 188 years of human achievement for humankind...so we can see and learn from the past...Wow! Not my most elegant words but you get the picture...
Here is the short YT clip from the article giving some explanation of seeing into the past with nothing visible in the present...
